Hi there,
I'm struggling to get things working in a very small test application I'm
creating. Using the base code I found here :
https://developer.gnome.org/gnome-devel-demos/unstable/beginner.js.html.en#tutorials,
I created the following :
#!/usr/bin/gjs
// Importing libraries
const GLib = imports.gi.GLib
, Gio = imports.gi.Gio
, Gtk = imports.gi.Gtk
, Lang = imports.lang
, Vte = imports.gi.Vte
;
// Application code
const HelloMe = new Lang.Class({
// Properties
Name: "Hello Me"
// Application initialization
, _init: function() {
this.application = new Gtk.Application();
// Declaring event listeners
this.application.connect('activate', Lang.bind(this, this.activate));
this.application.connect('startup', Lang.bind(this, this.startup));
}
// Application callbacks
, activate: function() {
this._window.present();
}
, startup: function() {
this.render();
}
, render: function() {
var term = new Vte.Terminal()
, testArray = new Array()
, anotherTestArray = new Array()
, pid
;
anotherTestArray.push('test');
testArray.push('/bin/bash');
pid = term.fork_command_full(
Vte.PtyFlags.DEFAULT
, '/home/me/'
, testArray
, anotherTestArray
, null
, null
, GLib.SpawnFlags.DO_NOT_REAP_CHILD
, null
, null
);
term.set_emulation('xterm');
term.show();
// Creating application's main window
this._window = new Gtk.ApplicationWindow({
application: this.application
, title: "Welcome to me"
, default_height: 200
, default_width: 400
, window_position: Gtk.WindowPosition.CENTER
});
// Adding the webview to the app and showing
this._window.add(term);
this._window.show_all();
}
});
let app = new HelloMe();
app.application.run(ARGV);
---------------------------------------------
I've been using two things to try and tackle the problem :
The Vte-2.90.gir file on my Ubuntu, located in /usr/lib/gir-1.0 where an
automatically generated documentation from the Vte C code source is
presented in xml format.
The following site :
http://www.roojs.com/seed/gir-1.2-gtk-3.0/gjs/index.html. Where those xml
files are presented in a html format, like a regular api.
Nevertheless, I get the following error :
gjs embed-term.js
GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will
not be saved or shared with other applications.
JS ERROR: !!! Exception was: Error: Unhandled array element type 14

"'
JS ERROR: !!! message = '"this._window is undefined"'
-----------------------------------------------
I gathered that both array I'm using aren't of the expected type. I tried
to look into the source code of Gtk itself, but I couldn't go further than
locating the problem to the gjs_array_to_array function in the following
file https://git.gnome.org/browse/gjs/tree/gi/arg.c?h=gnome-3-8 at line
876, where the element_type is deduced.
I couldn't find the place where the function g_type_info_get_tag was.
any help would be appreciated !
Thanks in advance
